RRB/ALP Samanya Vigyan evam Ganit Safalta Kosh

there are many books on this subject in the market but in most of the books you will find the same very old essays and their way of writing almost same. Writers hesitate to write on new topics, some future topics which are the need of the hour. Being the teacher of english, teaching for the last two decades to graduate to post graduate level.  I know what is required today. Keeping in mind the need of the hour  I am compiling this book of cutting edge essays, in which you will find something for everyone, you may be college student, appearing in competitive exam, department or banking exam. etc.
